On 2 and 3 June 2021, the VVP (Vertical Velocity Profiler) was put through its paces in the fresh water of the 10 m deep pit belonging to the well-known COMEX underwater works company. Fitted with the ice releases developed at MIO to free it of its ballast after each dive, the VVP carried out more than 80 ascending profiles at different speeds and with different configurations, in order to characterise its dynamics in a controlled environment. The measurements will enable us to assess its drag coefficient, as well as the frequency and amplitude of wake vortices as a function of the VVP's speed and configuration. This valuable information will be used to develop the methodology for deploying the VVP for measurements at sea during future oceanographic campaigns.<\/p>
